I'm on a Windows XP student's computer. When we get busy and start running R stuff, it hangs at random with the hour glass showing, but the system's cpu is not running at 100%. We sit and watch for a while, and then try alt-ctl-delete to kill the not responding program. In this case, I'm able to produce the problem almost every time by starting Rcmdr and running some graphs.
I'm suspecting that there may be some hardware problem, possibly overheating, but have no evidence for that guess. I can't find the error codes in the R docs (sorry). I think the following supplies the information that the posting guide asks for: > sessionInfo() R version 2.8.1 (2008-12-22) i386-pc-mingw32 locale: LC_COLLATE=English_United States.1252;LC_CTYPE=English_United States.1252;LC_MONETARY=English_United States.1252;LC_NUMERIC=C;LC_TIME=English_United States.1252 attached base packages: [1] stats graphics grDevices utils datasets methods base > library(Rcmdr) Loading required package: tcltk Loading Tcl/Tk interface ... done Loading required package: car Rcmdr Version 1.4-7 Attaching package: 'Rcmdr' The following object(s) are masked from package:tcltk : tclvalue > x<- rnorm(100) > Loading required package: rgl Loading required package: mgcv This is mgcv 1.5-0 .
